Description

Technical Field

[0001] The utility model belongs to the technical field of lithium battery production, and specifically relates to a stirring and batching device for lithium battery production. Background Art

[0002] With the rapid development of electronic technology, lithium batteries, as efficient and lightweight energy storage devices, have been widely used in many fields such as mobile communications, electric vehicles, and energy storage systems. In the production process of lithium batteries, the mixing and batching process plays a vital role in the quality and performance of the final product.

[0003] Traditional mixing and batching equipment used in lithium battery production suffers from a number of significant operational deficiencies. Early designs were relatively simple, typically consisting of multiple feed ports positioned above a container, into which various raw materials were poured and mixed. However, this crude feeding method made it impossible to precisely control the amount of each material added, resulting in frequent deviations in the material ratios. This lack of quantitative addition made it difficult to maintain a stable and accurate ratio of the various materials during each mixing process, directly impacting the performance consistency and quality reliability of lithium batteries.

[0004] Some slightly improved devices use separate storage silos to store raw materials, but when transporting the materials to the mixing area, they often rely on manual experience or simple mechanical control methods. Manual operation is not only labor-intensive and inefficient, but also easily affected by human factors, resulting in inaccurate material addition. Simple mechanical control methods, such as common valve control, have limited accuracy and cannot meet the high-precision material ratio requirements required for lithium battery production. In addition, because these devices cannot effectively prevent the continuous addition of materials during the mixing process, they can easily cause uneven mixing, resulting in large differences in the performance of lithium batteries produced from different batches.

[0005] To this end, we have proposed a stirring and batching device for lithium battery production, which can realize the quantitative addition of materials, ensure the accurate proportion of various materials during each stirring, and help improve the stability of product quality. Utility Model Content

[0006] The purpose of this utility model is to provide a stirring and batching device for lithium battery production, which can realize the quantitative addition of materials, ensure the accurate proportion of various materials during each stirring, and help improve the stability of product quality.

[0007] The technical solutions adopted in this application are as follows:

[0008] A stirring and batching device for lithium battery production, including a cylinder body. Two threaded holes are opened at the top of the cylinder body. A storage cylinder is installed inside each threaded hole. Two chutes are opened on the inner wall of the top of the cylinder body. A sliding plate is arranged inside each chute. A first through hole matching the threaded hole is opened on the sliding plate. And a batching pipe communicated with the first through hole is arranged at the bottom of the sliding plate. The batching pipe is a vertically communicated structure. A connecting plate is arranged on the batching pipe. The two connecting plates are symmetrically arranged. And meshing teeth are arranged on one side of the two connecting plates close to each other.

[0009] A first rotating component is arranged at the central position of the top of the cylinder body. A gear meshing with the meshing teeth is arranged on the first rotating component. And a support plate fitting the bottom of the batching pipe is arranged on the inner wall of the cylinder body. A second through hole is opened on the support plate.

[0010] Further, a feed pipe is arranged at the top of the storage cylinder.

[0011] Further, a smooth surface is arranged on the support plate.

[0012] Further, the first rotating component includes a first motor arranged at the center of the top of the cylinder body. A first rotating shaft is installed at the output end of the first motor. The bottom of the first rotating shaft penetrates through the cylinder body and is connected with the gear.

[0013] Further, a hollow cylinder is arranged on the side wall of the cylinder body. A movable plate is arranged inside the hollow cylinder. A moving rod is arranged on one side of the movable plate. One end of the moving rod far away from the movable plate penetrates out of the hollow cylinder and is connected with the batching pipe.

[0014] Further, a second motor is arranged at the bottom of the cylinder body. A second rotating shaft is installed at the output end of the second motor. The top of the second rotating shaft penetrates through the cylinder body. And a stirring rod is arranged at the position where the second rotating shaft penetrates through.

[0015] The technical effects obtained by this utility model are:

[0016] First, different materials are respectively fed into the two storage cylinders. At this time, under the action of gravity, the materials enter the batching pipe through the first through hole (at this time, such as Figure 2As shown, the support plate seals the bottom of the batching pipe, and the first through hole on the sliding plate aligns with the discharge port of the storage barrel inside the threaded hole. When the material fills the inside of the batching pipe, it achieves a quantitative effect. Then, when the material needs to be stirred, the first rotating assembly is activated. The first rotating assembly drives the gear to rotate, and the gear drives two meshing teeth to drive the connecting plate to make the two batching pipes move in opposite directions. At this time, the batching pipe drives the sliding plate inside the chute, so that the first through hole on the sliding plate is misaligned with the discharge port of the storage barrel inside the threaded hole, thereby preventing the material inside the storage barrel from entering the batching pipe. At the same time, the sliding plate moves on the support plate, so that the discharge port of the batching pipe aligns with the second through hole, so that the quantitative material enters the inside of the cylinder for stirring. This device can achieve the quantitative addition of materials, ensure the accurate proportion of various materials during each stirring, and contribute to improving the stability of product quality.

[0028] Its working principle is: first, different materials are respectively put into the two storage barrels 3, at this time, under the influence of gravity, the materials enter the inside of the dispensing pipe 7 through the first through hole 6 (at this time, Figure 2 As shown, the support plate 11 blocks the bottom of the dispensing pipe 7, and the first through hole 6 on the sliding plate 5 is aligned with the discharge port of the storage barrel 3 inside the threaded hole 2). When the material fills the inside of the dispensing pipe 7, a quantitative effect is achieved.

The gear 10 drives the two meshing teeth 9 to make the connecting plate 8 drive the two dispensing pipes 7 to do opposite movements. At this time, the dispensing pipe 7 drives the sliding plate 5 inside the chute 4, so that the first through hole 6 on the sliding plate 5 is misaligned with the discharge port of the storage barrel 3 inside the threaded hole 2, thereby preventing the material inside the storage barrel 3 from entering the dispensing pipe 7. At the same time, the sliding plate 5 moves on the support plate 11, so that the discharge port of the dispensing pipe 7 is aligned with the second through hole 12, so that a quantitative amount of material enters the cylinder 1 for stirring.

[0036] A discharge pipe is provided at the bottom of the cylinder 1, and a sealing cover is provided on the discharge pipe, through which the mixed material is discharged.

[0037] The working principle of this utility model is as follows: first, different materials are respectively put into the interior of the two storage barrels 3, at this time, due to the gravity, the materials enter the interior of the dispensing pipe 7 through the first through hole 6 (at this time, as shown in FIG. Figure 2 As shown, the support plate 11 blocks the bottom of the dispensing pipe 7, and the first through hole 6 on the sliding plate 5 is aligned with the discharge port of the storage barrel 3 inside the threaded hole 2).

Then, when the material needs to be stirred, the first rotating component is started, and the first rotating component drives the gear 10 to rotate. The gear 10 drives the two meshing teeth 9 to make the connecting plate 8 drive the two dispensing pipes 7 to do opposite movements. At this time, the dispensing pipe 7 drives the sliding plate 5 inside the chute 4, so that the first through hole 6 on the sliding plate 5 is misaligned with the discharge port of the storage barrel 3 inside the threaded hole 2, thereby preventing the material inside the storage barrel 3 from entering the dispensing pipe 7. At the same time, the sliding plate 5 moves on the support plate 11, so that the discharge port of the dispensing pipe 7 is aligned with the second through hole 12, so that a quantitative amount of material enters the cylinder 1 for stirring.
